The song was composed by Paul de Senneville and one Jean Baudlot. This was de Senneville's third consecutive Monegasque Eurovision entry, in 1977 and 1978 he had written "Une petite française" and "Les jardins de Monaco" in collaboration with Olivier Toussaint and the lyricists Jean Albertini and Didier Barbelivien. Composer Jean Baudlot, in turn, is in fact the same person as the artist Laurent Vaguener; this was a pseudonym occasionally used by Baudlot in the late 70s and early 80s, sometimes spelt Laurent Wagner.
"Notre vie c'est la musique" is an up-tempo disco track in praise of the power of music. Vaguener sings of his love for American popular music (blues and rock'n'roll), as well as the sounds of Paris. He explains that one of his great joys is when an attractive girl finds his music interesting and tells him "I love you".
